Hi i had a chest exray and am a survivor of poorly differentiated squamous cell carcinoma with a malignant fistula,,,,the chest xray stated there is a small faint nodule on the R midlung and it could represent confluent rib and vascular shadows although a small parenchymal nodule is possible it said also that the lungs are mildly hyper aerated can you shed light on what could be wrong ,,,,thank you Michelle
